Hi all,
I'm about to lose one very important vm. I shut down this vm for maintenance and then I moved the four disks to a new created lun. This vm has 2 snapshots.
After successful move, the vm refuses to start with this message:
Bad volume specification {u'index': 0, u'domainID': u'961ea94a-aced-4dd0-a9f0-266ce1810177', 'reqsize': '0', u'format': u'cow', u'bootOrder': u'1', u'discard': False, u'volumeID': u'a0b6d5cb-db1e-4c25-aaaf-1bbee142c60b', 'apparentsize': '2147483648 <tel:%28214%29%20748-3648>', u'imageID': u'4a95614e-bf1d-407c-aa72-2df414abcb7a', u'specParams': {}, u'readonly': u'false', u'iface': u'virtio', u'optional': u'false', u'deviceId': u'4a95614e-bf1d-407c-aa72-2df414abcb7a', 'truesize': '2147483648 <tel:%28214%29%20748-3648>', u'poolID': u'48ca3019-9dbf-4ef3-98e9-08105d396350', u'device': u'disk', u'shared': u'false', u'propagateErrors': u'off', u'type': u'disk'}.
I tried to merge the snaphots, export , clone from snapshot, copy disks, or deactivate disks and every action fails when it is about disk.
I began to dd lv group to get a new vm intended to a standalone libvirt/kvm, the vm quite boots up but it is an outdated version before the first snapshot. There is a lot of disks when doing a "lvs | grep 961ea94a" supposed to be disks snapshots. Which of them must I choose to get the last vm before shutting down? I'm not used to deal snapshot with virsh/libvirt, so some help will be much appreciated.
The disks which you want to copy should contain the entire volume chain. Based on the log you mentioned, It looks like this image is problematic:
=C2=A0 storage id: '961ea94a-aced-4dd0-a9f0-266ce1810177', =C2=A0 imageID': u'4a95614e-bf1d-407c-aa72-2df414abcb7a =C2=A0 volumeID': u'a0b6d5cb-db1e-4c25-aaaf-1bbee142c60b'
What if you try to deactivate this image and try to run the VM, will it run?
I already tried to do what you suggest, but it is the same, and more this disk is part of a volume groupe, so I can't boot the vm without it.
Is there some unknown command to recover this vm into ovir=
t?
Thank you in advance.

Beside specific oVirt answers, did you try to get informations about the snapshot tree with qemu-img info --backing-chain on the adequate /dev/... logical volume? As you know how to dd from LVs, you could extract every needed snapshots files and rebuild your VM outside of oVirt. Then take time to re-import it later and safely.
